Re: OT Barcode Scanner- how do I get it to work

[Alan Shields <alan@xxxxxxx>]

Run a terminal emulator to see what it's sending ( you may need to try
several baud rates till you get the right one)

This type is more difficult to cater for than the keyboard wedge ones,
you'll either need a special driver or cater for it in your code, the
latter option is nicer because you don't need the focus to be on a 
specific field waiting for the barcode data to arrive.

With most of these things the manual has a load of barcodes in it for
configuration of things like serial speed, barcode standards to recognise
(2 of 5, codabar, 3 of 9 etc etc) and lead in and termination characters to
send. Most of these tend to recommend disabling barcode standards that are
not going to be used to increase reading accuracy, This is bad news for you
if you can't get the manual and the last user had it configured solely for
3 of 9.
